Ensemble forecasts from GFS and ECMWF models indicate a daytime high near 21-22°C at Buenos Aires' Ezeiza Airport on April 4, reflecting trader sentiment clustered around 20-21-22°C outcomes amid 1-3°C spreads that capture inherent short-range uncertainty. This follows a recent heatwave with record-breaking minimums earlier this week and today's forecasted 27°C maximum under humid, thundery conditions, as a frontal passage ushers southeast winds, decreasing clouds, and drier air to temper peak heating. Differentiating factors include the precise timing of afternoon cloud dissipation and sea breeze intensification, which influence boundary layer mixing and surface temperatures; climatological April highs average 23°C but vary with synoptic patterns. New observational data and model runs from Servicio Meteorológico Nacional overnight could refine probabilities before resolution.
